How 2,000 Chitlapakkam Residents Revived a Sewage-Choked Lake
Chitlapakkam had a large lake, but it was filled with sewage, garbage and plants.
The dirty lake could not provide clean water to nearby families.
Many borewells became dry or produced contaminated water, so residents had to buy water.
People first tried petitions, protests and other peaceful actions.
When little changed, more than 2,000 residents cleaned the lake themselves in 2019.
Their campaign helped secure ₹25 crore for restoration.
Workers stopped sewage from entering, drained the lake, removed dirty soil and made it deeper.
Today, people walk, exercise and spend time around the restored lake.
The lake also helps recharge groundwater and reduce flooding risks.
Chitlapakkam Lake, a 50-acre waterbody near Chennai, was polluted by sewage, garbage and water hyacinth.
Drying borewells and contaminated groundwater left residents dependent on purchased water despite living beside the lake.
After petitions and protests achieved little, more than 2,000 residents began a mass cleaning drive on 2 June 2019.
The restoration used a four-step process involving sewage diversion, draining, desilting and deepening the lake by 2.5 metres.
The revived lake now supports groundwater recharge and includes walking paths, greenery, an open-air gym and recreational spaces.
